The Arch User Repository (AUR) is a community-driven repository for Arch users. It contains package descriptions (PKGBUILDs) that allow you to compile a package from source with makepkg and then install it via pacman. The AUR was created to organize and share new packages from the community and to help expedite popular packages' inclusion into the community repository. This document explains how users can access and utilize the AUR.
A good number of new packages that enter the official repositories start in the AUR. In the AUR, users are able to contribute their own package builds (PKGBUILD and related files). The AUR community has the ability to vote for packages in the AUR. If a package becomes popular enough — provided it has a compatible license and good packaging technique — it may be entered into the community repository (directly accessible by pacman or abs).
Getting started
Users can search and download PKGBUILDs from the AUR Web Interface. These PKGBUILDs can be built into installable packages using makepkg, then installed using pacman.
- Ensure the base-devel package group is installed in full (
pacman -S --needed base-devel
). - Glance over the #FAQ for answers to the most common questions.
- You may wish to adjust
/etc/makepkg.conf
to optimize for your processor prior to building packages from the AUR. A significant improvement in compile times can be realized on systems with multi-core processors by adjusting the MAKEFLAGS variable. Users can also enable hardware-specific optimizations in GCC via the CFLAGS variable. See makepkg for more information.
It is also possible to interact with the AUR through SSH: type ssh aur@aur.archlinux.org help
for a list of available commands.
History
In the beginning, there was ftp://ftp.archlinux.org/incoming
, and people contributed by simply uploading the PKGBUILD, the needed supplementary files, and the built package itself to the server. The package and associated files remained there until a Package Maintainer saw the program and adopted it.
Then the Trusted User Repositories were born. Certain individuals in the community were allowed to host their own repositories for anyone to use. The AUR expanded on this basis, with the aim of making it both more flexible and more usable. In fact, the AUR maintainers are still referred to as TUs (Trusted Users).
Between 2015-06-08 and 2015-08-08 the AUR transitioned from version 3.5.1 to 4.0.0, introducing the use of Git repositories for publishing the PKGBUILDs. Existing packages were dropped unless manually migrated to the new infrastructure by their maintainers.
Git repositories for AUR3 packages
The AUR Archive on GitHub has a repository for every package that was in AUR 3 at the time of the migration. Alternatively, there is the aur3-mirror repository which provides the same.
Installing packages
Installing packages from the AUR is a relatively simple process. Essentially:
- Acquire the build files, including the PKGBUILD and possibly other required files, like systemd units and patches (often not the actual code).
- Verify that the PKGBUILD and accompanying files are not malicious or untrustworthy.
- Run
makepkg -si
in the directory where the files are saved. This will download the code, resolve the dependencies with pacman, compile it, package it, and install the package.
Prerequisites
First ensure that the necessary tools are installed by installing the base-devel group in full which includes make and other tools needed for compiling from source.
Next choose an appropriate build directory. A build directory is simply a directory where the package will be made or "built" and can be any directory. The examples in the following sections will use ~/builds
as the build directory.
Acquire build files
Locate the package in the AUR. This is done using the search field at the top of the AUR home page. Clicking the application's name in the search list brings up an information page on the package. Read through the description to confirm that this is the desired package, note when the package was last updated, and read any comments.
There are several methods for acquiring the build files:
- Clone the git repository that is labelled as the "Git Clone URL" in the "Package Details". This is the preferred method.
$ git clone https://aur.archlinux.org/package_name.git
- An advantage of this method is that you can easily get updates to the package via
git pull
.
- Download the build files with your web browser by clicking the "Download snapshot" link under "Package Actions" on the right hand side. This will download a compressed file, which must be extracted (preferably in a directory set aside for AUR builds)
$ tar -xvf package_name.tar.gz
- Similarly, you can download a tarball from the terminal (and extract it):
$ curl -L -O https://aur.archlinux.org/cgit/aur.git/snapshot/package_name.tar.gz
Build and install the package
Change directories to the directory containing the package's PKGBUILD.
$ cd package_name
View the contents of all provided files. For example, to use the pager less to view PKGBUILD
do:
$ less PKGBUILD
- To view changes since the last git commit you can use
git show
. - To view changes since the last commit using vimdiff, do
git difftool @~..@ vimdiff
. The advantage of vimdiff is that you view the entire contents of each file along with indicators on what has changed.
Make the package. After manually confirming the contents of the files, run makepkg as a normal user:
$ makepkg -si
-s
/--syncdeps
automatically resolves and installs any dependencies with pacman before building. If the package depends on other AUR packages, you will need to manually install them first.-i
/--install
installs the package if it is built successfully. Alternatively the built package can be installed withpacman -U package.pkg.tar.xz
.
Other useful flags are
-r
/--rmdeps
removes build-time dependencies after the build, as they are no longer needed. However these dependencies may need to be reinstalled the next time the package is updated.-c
/--clean
cleans up temporary build files after the build, as they are no longer needed. These files are usually needed only when debugging the build process.
Feedback
The AUR Web Interface has a comments facility that allows users to provide suggestions and feedback on improvements to the PKGBUILD contributor. Avoid pasting patches or PKGBUILDs into the comments section: they quickly become obsolete and just end up needlessly taking up lots of space. Instead email those files to the maintainer, or even use a pastebin.
One of the easiest activities for all Arch users is to browse the AUR and vote for their favourite packages using the online interface. All packages are eligible for adoption by a TU for inclusion in the community repository, and the vote count is one of the considerations in that process; it is in everyone's interest to vote!
Sharing and maintaining packages
Users can share PKGBUILDs using the Arch User Repository. It does not contain any binary packages but allows users to upload PKGBUILDs that can be downloaded by others. These PKGBUILDs are completely unofficial and have not been thoroughly vetted, so they should be used at your own risk.
Submitting packages
If you are unsure in any way about the package or the build/submission process even after reading this section twice, submit the PKGBUILD to the AUR mailing list, the AUR forum on the Arch forums, or ask on our IRC channel for public review before adding it to the AUR.
Rules of submission
When submitting a package to the AUR, observe the following rules:
- The submitted PKGBUILDs must not build applications already in any of the official binary repositories under any circumstances. Check the official package database for the package. If any version of it exists, do not submit the package. If the official package is out-of-date, flag it as such. If the official package is broken or is lacking a feature, then please file a bug report.
- Exception to this strict rule may only be packages having extra features enabled and/or patches in comparison to the official ones. In such an occasion the
pkgname
should be different to express that difference. For example, a package for GNU screen containing the sidebar patch could be namedscreen-sidebar
. Additionally theprovides=('screen')
array should be used in order to avoid conflicts with the official package.
- Check the AUR if the package already exists. If it is currently maintained, changes can be submitted in a comment for the maintainer's attention. If it is unmaintained or the maintainer is unresponsive, the package can be adopted and updated as required. Do not create duplicate packages.
- Make sure the package you want to upload is useful. Will anyone else want to use this package? Is it extremely specialized? If more than a few people would find this package useful, it is appropriate for submission.
- The AUR and official repositories are intended for packages which install generally software and software-related content, including one or more of the following: executable(s); config file(s); online or offline documentation for specific software or the Arch Linux distribution as a whole; media intended to be used directly by software.
- Do not use
replaces
in an AUR PKGBUILD unless the package is to be renamed, for example when Ethereal became Wireshark. If the package is an alternate version of an already existing package, useconflicts
(andprovides
if that package is required by others). The main difference is: after syncing (-Sy) pacman immediately wants to replace an installed, 'offending' package upon encountering a package with the matchingreplaces
anywhere in its repositories;conflicts
, on the other hand, is only evaluated when actually installing the package, which is usually the desired behavior because it is less invasive.
- Submitting binaries should be avoided if the sources are available. The AUR should not contain the binary tarball created by makepkg, nor should it contain the filelist.
- Please add a comment line to the top of the
PKGBUILD
file which contains information about the current maintainers and previous contributors, respecting the following format. Remember to disguise your email to protect against spam. Additional or unneeded lines are facultative.
- If you are assuming the role of maintainer for an existing PKGBUILD, add your name to the top like this
# Maintainer: Your Name <address at domain dot tld>
- If there were previous maintainers, put them as contributors. The same applies for the original submitter if this is not you. If you are a co-maintainer, add the names of the other current maintainers as well.
# Maintainer: Your name <address at domain dot tld> # Maintainer: Other maintainer's name <address at domain dot tld> # Contributor: Previous maintainer's name <address at domain dot tld> # Contributor: Original submitter's name <address at domain dot tld>
Authentication
For write access to the AUR, you need to have an SSH key pair. The content of the public key needs to be copied to your profile in My Account, and the corresponding private key configured for the aur.archlinux.org
host. For example:
~/.ssh/config
Host aur.archlinux.org IdentityFile ~/.ssh/aur User aur
You should create a new key pair rather than use an existing one, so that you can selectively revoke the keys should something happen:
$ ssh-keygen -f ~/.ssh/aur
Creating package repositories
If you are creating a new package from scratch, establish a local Git repository and an AUR remote by cloning the intended pkgbase. If the package does not yet exist, the following warning is expected:
$ git clone ssh://aur@aur.archlinux.org/pkgbase.git
Cloning into 'pkgbase'... warning: You appear to have cloned an empty repository. Checking connectivity... done.
pkgbase
matches a deleted package.If you already have a package, initialize it as a Git repository if it isn't one, and add an AUR remote:
$ git remote add label ssh://aur@aur.archlinux.org/pkgbase.git
Then fetch this remote to initialize it in the AUR.
pkgbase
matches a deleted package.Publishing new package content
git config user.name "..."
and git config user.email "..."
.To upload or update a package add at least PKGBUILD and .SRCINFO then any new or modified .install files, patches or other local source files; commit with a meaningful commit message, and finally push the changes to the AUR.
For example:
$ makepkg --printsrcinfo > .SRCINFO $ git add -f PKGBUILD .SRCINFO $ git commit -m "useful commit message" $ git push
- After modifying a package, except for very minor changes (such as fixing a typo) that would not require re-installation of the package, update its version accordingly.
- Regenerate
.SRCINFO
after updating suchPKGBUILD
metadata in order to publish it in the AUR. - If
.SRCINFO
was not added before your first commit, add it by rebasing with --root or filtering the tree so the AUR will permit your initial push.
Maintaining packages
- Check for feedback and comments from other users and try to incorporate any improvements they suggest; consider it a learning process!
- Please do not leave a comment containing the version number every time you update the package. This keeps the comment section usable for valuable content mentioned above.
- Please do not just submit and forget about packages! It is the maintainer's job to maintain the package by checking for updates and improving the PKGBUILD.
- If you do not want to continue to maintain the package for some reason,
disown
the package using the AUR web interface and/or post a message to the AUR Mailing List. If all maintainers of an AUR package disown it, it will become an "orphaned" package.
Other requests
Deletion, merge, and orphan requests can be created by clicking on the "Submit Request" link under "Package Actions" on the right hand side. This will send a notification email to the current maintainer and to the aur-requests mailing list for discussion. A Trusted User will then either accept or reject the request.
Deletion
You may request to unlist a pkgbase
from the AUR. A short note explaining the reason for deletion is required, as well as supporting details (like when a package is provided by another package, if you are the maintainer yourself, it is renamed and the original owner agreed, etc).
- It is not sufficient to explain why a package is up for deletion only in its comments because as soon as a TU takes action, the only place where such information can be obtained is the aur-requests mailing list.
- Deletion requests can be rejected, in which case if you are the maintainer you will likely be advised to disown the package to allow adoption by another maintainer.
- After a package is "deleted", its git repository remains available for cloning.
Merge
You may request to delete a pkgbase
and transfer its votes and comments to another pkgbase
. The name of the package to merge into is required.
Orphan
You may request that a pkgbase
be disowned. These requests will be granted after two weeks if the current maintainer did not react.
Web interface translation
See i18n.txt in the AUR source tree for information about creating and maintaining translation of the AUR web interface.
Comment syntax
The Python-Markdown syntax is supported in comments. It provides basic Markdown syntax to format comments. Note this implementation has some occasional differences with the official syntax rules. Commit hashes to the Git repository of the package and references to Flyspray tickets are converted to links automatically. Long comments are collapsed and can be expanded on demand.
FAQ
What is the AUR?
The AUR (Arch User Repository) is a place where the Arch Linux community can upload PKGBUILDs of applications, libraries, etc., and share them with the entire community. Fellow users can then vote for their favorites to be moved into the community repository to be shared with Arch Linux users in binary form.
What kind of packages are permitted on the AUR?
The packages on the AUR are merely "build scripts", i.e. recipes to build binaries for pacman. For most cases, everything is permitted, subject to the abovementioned usefulness and scope guidelines, as long as you are in compliance with the licensing terms of the content. For other cases, where it is mentioned that "you may not link" to downloads, i.e. contents that are not redistributable, you may only use the file name itself as the source. This means and requires that users already have the restricted source in the build directory prior to building the package. When in doubt, ask.
How can I vote for packages in the AUR?
Sign up on the AUR website to get a "Vote for this package" option while browsing packages. After signing up it is also possible to vote from the commandline with aurvoteAUR, aurvote-gitAUR or aur-auto-vote-gitAUR.
Alternatively, if you have set up ssh authentication as above, you can directly vote from the command line using your ssh key. This means that you won't need to save or type in your AUR password.
ssh aur@aur.archlinux.org vote <PACKAGE_NAME>
What is a Trusted User / TU?
A Trusted User, in short TU, is a person who is chosen to oversee AUR and the community repository. They are the ones who maintain popular PKGBUILDs in community, and overall keep the AUR running.
What is the difference between the Arch User Repository and the community repository?
The Arch User Repository is where all PKGBUILDs that users submit are stored, and must be built manually with makepkg. When PKGBUILDs receive enough community interest and the support of a TU, they are moved into the community repository (maintained by the TUs), where the binary packages can be installed with pacman.
Foo in the AUR is outdated; what should I do?
First, you should flag the package out-of-date indicating details on why the package is outdated, preferably including links to the release announcement or the new release tarball. You should also try to reach out to the maintainer directly by email. If there is no response from the maintainer after two weeks, you can file an orphan request. This means you ask a Trusted User to disown the package base. This is to be done only if the package requires maintainer action, that he/she is not responding and you already tried to contact him/her previously.
In the meantime, you can try updating the package yourself by editing the PKGBUILD locally. Sometimes, updates do not require changes to the build or package process, in which case simply updating the pkgver
or source
array is sufficient.
Foo in the AUR does not compile when I run makepkg; what should I do?
You are probably missing something trivial.
- Upgrade the system before compiling anything with
makepkg
as the problem may be that your system is not up-to-date. - Ensure you have both base and base-devel groups installed.
- Try using the
-s
option withmakepkg
to check and install all the dependencies needed before starting the build process.
Be sure to first read the PKGBUILD and the comments on the AUR page of the package in question. The reason might not be trivial after all. Custom CFLAGS, LDFLAGS and MAKEFLAGS can cause failures. It is also possible that the PKGBUILD is broken for everyone. If you cannot figure it out on your own, just report it to the maintainer e.g. by posting the errors you are getting in the comments on the AUR page.
To check if the PKGBUILD is broken, or your system is misconfigured, consider building in a clean chroot. It will build your package in a clean Arch Linux environment, with only (build) dependencies installed, and without user customization. To do this install devtools and run extra-x86_64-build
instead of makepkg
. For multilib packages, run multilib-build
See DeveloperWiki:Building in a clean chroot for more information. If the build process still fails in a clean chroot, the issue is probably with the PKGBUILD.
ERROR: One or more PGP signatures could not be verified!; what should I do?
Most likely you do not have the required public key(s) in you personal keyring to verify downloaded files. If one or more .sig files are downloaded while building the package, makepkg will automatically verify corresponding file(s) with the public key of its signer. If you do not have the required key in your personal keyring, makepkg will fail to do the verification.
The recommended way to deal with this problem is to import the required public key, either manually or from a key server. Often, you can simply find the fingerprint of the needed public key(s) in the validpgpkeys section of the PKGBUILD.
How do I create a PKGBUILD?
The best resource is the wiki page about creating packages. Remember to look in AUR before creating the PKGBUILD as to not duplicate efforts.
I have a PKGBUILD I would like to submit; can someone check it to see if there are any errors?
If you would like to have your PKGBUILD reviewed, post it on the aur-general mailing list to get feedback from the TUs and fellow AUR members. You could also get help from the IRC channel, #archlinux-aur on irc.freenode.net. You can also use namcap to check your PKGBUILD and the resulting package for errors.
How to get a PKGBUILD into the community repository?
Usually, at least 10 votes are required for something to move into community. However, if a TU wants to support a package, it will often be found in the repository.
Reaching the required minimum of votes is not the only requirement, there has to be a TU willing to maintain the package. TUs are not required to move a package into the community repository even if it has thousands of votes.
Usually when a very popular package stays in the AUR it is because:
- Arch Linux already has another version of a package in the repositories
- Its license prohibits redistribution
- It helps retrieve user-submitted PKGBUILDs. AUR helpers are unsupported by definition.
See also Rules for Packages Entering the community Repo.
How can I speed up repeated build processes?
See Makepkg#Improving compile times.
What is the difference between foo and foo-git packages?
Many AUR packages are presented in regular ("stable") and development versions ("unstable"). A development package usually has a suffix such as -cvs
, -svn
, -git
, -hg
, -bzr
or -darcs
. While development packages are not intended for regular use, they may offer new features or bugfixes. Because these packages download the latest available source when you execute makepkg
, a package version to track possible updates is not directly available for these. Likewise, these packages cannot perform an authenticity checksum, instead it is relied on the maintainer(s) of the Git repository.
See also System maintenance#Use proven software packages.
Why has foo disappeared from the AUR?
It is possible the package has been adopted by a TU and is now in the community repository.
Packages may be deleted if they did not fulfill the #Rules of submission. See the aur-requests archives for the reason for deletion.
If the package used to exist in AUR3, it might not have been migrated to AUR4. See the #Git repositories for AUR3 packages where these are preserved.
How do I find out if any of my installed packages disappeared from AUR?
The simplest way is to check the HTTP status of the package's AUR page:
$ comm -23 <(pacman -Qqm | sort) <(curl https://aur.archlinux.org/packages.gz | gzip -cd | sort)
How can I obtain a list of all AUR packages?
- https://aur.archlinux.org/packages.gz
- Use
aurpkglist
from python3-aurAUR
